Chillin' in My 30s after Getting Fired from the Demon King's Army

Dariel, raised by Granverza, one of the Four Heavenly Generals, spent over 30 years serving the Demon King's army without possessing any magical abilities. Upon Granverza's son Bashubaza taking over as general, Dariel was promptly fired. After losing his home and job, he encountered Marika, a human girl being chased by a monster, and intervened to save her. In return for his help, Marika invited Dariel to stay in her village, where he discovered a surprising truth about his human identity. As a human with exceptional abilities, Dariel now risks being drawn into the conflict between humans and demons.
